SHUTTLE.

Specification of Letters Patent.

Application leil February 5, i912. Serial No. 675,408.

ties, of which thefollowing is a description,

reference ,being-had to/ the accompanying drawingsywhich are a part of-this specification. f ji' 'p This invention nrelates to shuttles for Wire weaving and has for'its lobject to provide a `double setof supporting rollers on which the shuttle travels, one roller of each set being movable vertically 'at the end ofthe travel of the shuttle wherebythe shuttletravels onv one setpof 'rollers in traveling inone direction and on theother set of rollers in traveling in the other direction. A

Another object of the invention is togive to the rolle-rsofthe two sets a different angularity with relation to the direction of travel of 'the shuttle whereby lthe shuttle will have a tendency to' travel close to 'the reed in either direction of ltravel thereof.

With. the above A'ami other objects inl-view the invention consist'sin the shuttle for wire weaving as herein claimed, and all equiva- 3': -mounted inthe arms of the swinging'lrames lents. Referringlto the accompanying drawings` in which like characters of referenfce indi# cate the same parts in the dill'erent'views2- Figure 1 .is a plan view of a shuttle constructed in accordance with` thisinvention; Fig. 2 is a vbottom view'th'ereof.; Fig. 3 is a sectional side elevation thereof; Fig. 4l is a detail sectional view Opneendfthereo; and, Fig. 5 is a transverse 'sectional vview through the d etent for the swinging bobbin carrier. i f

In these drawings 10'indicates a shuttle body having a central opening in which a swinging bobbin carrier 11 is pivotally mounted at 12 to be capable of reversing the position of the bobbin at each end of thel travel of the shuttle, said bobbin carrier 11 having an arm 13 carrying a guideeye 14 for the wire 15 let off from the bobbin 16 and adapted to enter slots at the ends of the central opening of 'the shuttle and strike against stop plates 17 to limit the throw of the bobbin carrier. In each of these slots is a spring pressed detent pin 1 8 which is engaged by the arm 13 and-said arm has beveled notches 19 at its edges to force the detent pin back when the arm enters the slot jam nut.

and also has a shallow recess 20`at its mid- '.dle portion to be engaged by the detent for tral opening the shuttle i'slprovided with recesses o n its under surface at each end thereof and in these. recesses are pivotally mounted C-shaped swinging frames 21 by means of trunnion screws 22 threaded through the sides of the shuttle and entering sockets provided for them as shown in Fig. 4. rIfhese Ratented Dee. 1, 1914. i

frames 21 form swinging roller frames y which areadapted to be engaged by the end y of the arm 13 and swung against the pressure of' springs 23- t0 lower their free ends. Between these free ends of the roller frames 21 are mounted rollers 24 which may for convenience be formed of two roller sections.` one having a screw' 26 embedded in. it and projectingtherefromfto' form one trunnion bearingwhile the other is threaded on the end of said screw and carriesl a trunnion plate 27 to form the other trunnion bearing for the roller. AlVith this .construction the two trunnion bearings are adj u stable'toward or away lfrom each other by turning one `roller section withrelation'totheother and this allows of the roller being'conveniently Q1." A jam nut 28 is threaded ,onthescrew Q6 to'bear against the adjustable roller member and lock it in itsA adjustment on the screw andy the other roller member is preferably provided'with a .recess to Areceive said its axis at right angles .to the axis of the shuttle proper or the line of direction of travel of the shuttle `andby. the swinging movements of the rollen frame 21 isfraisedor loweredwithrelation to the shuttle, its lower position, as shown in Fig.

3, being occupied when thearngl is in engagementwith itsframe of the recesses at the end v'of thev shuttle is also provided with an angular ifixedfroller 29, `that is, its axis is at an angle to the axis or the line ofvdirection of travel 'of the shuttle f proper and is immovable vertically or otherwise and these fixed rollers at the two'ends of the shuttle are setat opposite angles so that when either of them 'is in bearing on the shuttleboard, which as will be later seen is only when the shuttle moves with it in advance, such angularity causes it ,to lead the shuttle toward the reed and thus lprevent the shuttle straying from its proper course.

This roller 2.4 is desirably set with other roller 24 on the swinging frame which In either position of the bobbin carrier'l its arm 13 engages one/0f the swinging frames 21 to'hold the roller thereof at its lower position which is lower than the fixed roller at1 that end of the shuttle and the is not engaged by the arm 13 is in its upper position Winches higher than the iii/ed roller at that end idf the shuttle.. Thus the shuttle 'isv always resting upon the fixed oblique roller 29 at the front end thereof and upon the vertically movable transverse roller 24 ,at the rear end thereof, and at 'the' Aend of the travel of the shuttle in one direction, the reversal of the position of the bobbin carrier causes the reversal of the positions of the` adjustable rollers so thaj/Qthis' .by Letters Patent is:

1. A shuttle, comprisingV a shuttlebody provided with a pair of rollers at each end,

one of the rollers of each pair being set at an oblique position, and means yfor moving one of the rollers of each pair vertically to cause it to take a position higher or lower than the other roller of the pair.

2. A shuttle, comprising a shuttle body, a pair o f supporting rollers at each end thereof, one roller of each pair being oblique to the shuttle and the oblique rollers having their angularity of position in opposite directions, and one of the rollers of each pair being mounted to have a vertical ad1ustment to assume a position higher than the other roller of the pair or to assume a position lower than the other roller of the pair, a reversible bobbin carrier mounted on the shuttle adapted to be changed in position at the end of the travel ofthe shuttle in each direction, and a connection between the bobbin carrier and the adjustable rollers for effecting the adjustment of the rollers by the change in position4 of the bobbin carrier.

3. A shuttle, comprising a shuttle body, a pair of rollers at each end of the shuttle body, one of the roller-sof each pair having an oblique position with relation to the shuttle body, a frame pivotally mounted at each end of the shuttle body, one of the rollers lat that end of the shuttle body being mounted therein and adapted by the pivotal movements of the frame to have a vertical adjustment to permit it to stand lower than the other roller of the pair or higher than the 4other roller .of the pair, and means for swinging the frames.

LA shuttle, comprising a shuttle body, a swinging frame at each end thereof, a

vpair of rollers at each end ofthey shuttle body, one of which is`journaledl in the shuttle body and the other is jonrnaled in the swinging frame to be moved bythe swinging frame higher than ory lower thanv the roller journaled in the shuttle body, a bobbin carrier pivotally lmounted on the shuttle body and adaptedto have its position` reversed at the end of travelfof' the shuttle in either direction, and an armen the bobbin the swinging pivotally mounted'in a central opening of the shuttle body and adapted to have its position reversed ,at the end of travel of the shuttle in either direction, an arm Aon the bobbin carrier adapted to engage and moveu the swinging frames against the action of their springs, and a spring detent for engaging and holding the bobbin/carrier in either position thereof.V

6. A roller support for the ends of shuttles, comprisinga roller fixed in position, a frame having fixed oppositev bearings, a roller journaled lin the bearings comprising a pair of roller members, a screw fixed in one roller member and forming a trunnion therefor, the other roller member being adjustably vthreaded on the screw, a trunnion on said other roller member, a set nut on the screw for locking said other member in its adjustments, and means for moving the frame to carry the roller thereof higher than or lower than the fixed roller, one ofthe rollers of each set being at an oblique position with relation to the other.

In testimony whereof, I affix my signature, in presence of two witnesses.
